SAN D-BAN D.

SPECIFICATION forming part of Letters Patent No. 447,288, dated March 3,1891. Application filed July 26, 1890. Serial No. 360,031. (No model.)

To all whom it may concern..-

Be it known that I, ALBERT BALL, a resident of Olaremont, in the countyof Sullivan and State of New Hampshire, have invented certain new anduseful Improvements in Sand-Bands; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled the art to which it pertains to make and usethe same.

The object of the invention. is to simplify and cheapen the constructionof sand-bands and of the means of connecting them with an axle of awheeled vehicle. Heretofore the shells of sand-bands have been providedwith an inner inturned flange, which was clamped between ascrew-threaded nut placed within the shell adjacent to the .fiange andan exteriorly-screw-thread ed holder fitted on the axle. This holder hasbeen made in the form of a mutilated or incomplete ring, being slottedfor the reception of the axle. An extension or arm of said holder wasembraced by the ordinary yoke, which holds together the wooden andmetallic sections of the usual form of carriage-axle and was therebyclamped to the bottom of the axle. By the present improvement the innerscrew-threaded ring is dispensed with and an annular band or washer issubstituted, which band is clamped upon an inturned flange of the shellby means of a projection or projections from the head, which, being ofmalleable metal, are adapted to be swaged or. forced down upon the bandand bind it to said head. In my application filed of even date herewithis shown a head secured directly to the shell by forcing the metal ofthe head upon the same. The present case relates to similar means ofbinding an annular washer or ring upon an inturned flange of the shellby clinching or .swaging portions of the head thereon in such manner asto grip the flange between the washer and the head. The holder abovereferred to is provided exteriorly on its main part with screw-threads,which are continuous, with others formed on the axle upon which theinteriorly-screw-threaded head of the sand-band is screwed.

According to the present improvement the head of the sand-box is securedto this holder by an externally -situated screw passing through the ringportion of the head and bearing upon the exterior of the holder, saidring portion being specially formed for the purpose.

The invention consists in the construction herein described andparticularly pointed out.

In the drawings, Figure l is a central longitudinal section of asandband orbox. Fig.

2 is a similar view of the same secured upon an axle. Fig. 3 is a likeView of a modified form. Fig. at is a plan of a clamping ring or washer.Fig. 5 is a central longitudinal section of said ring; and Fig. 6 is aplan of the ring secured upon the head, the shell being omitted.

Reference-letter A indicates a sheet-metal shell of a sand band or boxprovided with an inturned flange 0.

D denotes a head having a screw-threaded opening adapted to be screwedupon the axle, and K a clamping-ring. The flange G is secured betweenthe rim of the head and said ring K by a projection L, formed integrallyL is a comupper or wooden section of the axle and the exterior of thebottom and sides of the holder have continuous screw-threads, whichadapt them to engage the screw-threaded opening of the head.

G is a set-screw passing through an exteno sion of the ring of the headin an inclined direction and engaging the holder in manner to lock themtogether. Heretofore a screw for a similar purpose has been placedwithin the sand-box. Such location is objectionable, as

it necessitates locating ahole in the sandband adjacent to the screw,and also requires a considerable inward extension of the ring of thehead and holder to furnish a seat for the screw. By the presentarrangement the screw is easily made accessible, and no special openingin the shell for its manipulation is required. To provide for this Iprolong the walls of the screw-threaded opening in the head toward thebody of the axle sufficiently to provide room for a seat for the screwoutside the shell, as shown, the projection of the wall-opening beingindicated by D.

I am aware that sand-bands have been provided with flanges that wereheld between disks and nuts, said nuts working on the axlespindle andadapted to force the flanges against the disks, the latter beingsupported by shoulders on the axle, and such devices are not of myinvention.

IIaving now described my invention, what I desire to secure by LettersPatent is- 1. In a sand hand or box, ashellhaving' an inturned flange, aband or washer, a head provided with a screw-threaded opening orspecification in the presence of two subscrib- 3o ing witnesses.

ALBERT EALL.
